I hope I can get a few dumb questions answered. Maybe some others can benefit too.

I've never done serious care for my hair before. What should I start off using? What should I avoid? From my lurking I've gathered I should try coconut oil, but where do I get it from? Is there a specific type, or is coconut oil just coconut oil?

I have ridiculously fine hair with a high rate of shedding and split ends.
